I confirm that my 565 only allows width setting up to 1.0 while Malcolm above refers to 1.3. Seem to remember my 568.2mm allows up to 1.5 so something has changed.

I'll try my set-up with another source, satellite used before was just convenient. Maybe a music source will be more revealing?

In the spirit of Spinaltap, I would like to confirm that I am not involved in the corrupt theft of a global sport.
